Is multus-cni v3.9.3-thick-amd64 THICK or THIN Plugin?

[hikkart]

Hi Team,

Configured multus-cni with Daemonset-thick-plugin yaml v3.9.3 with container Image: v3.9.3-thick-amd64.

Daemonset-thick-plugin yaml: https://github.com/k8snetworkplumbingwg/multus-cni/blob/v3.9.3/deployments/multus-daemonset-thick-plugin.yml Container Image: https://github.com/k8snetworkplumbingwg/multus-cni/pkgs/container/multus-cni/61872617?tag=v3.9.3-thick-amd64

Expected multus-shim (as in 4.0.2) but ended up with multus binary like thin plugin.

Also found that config yaml shows type=multus and configuration is similar to THIN plugin config.

Is multus-cni v3.9.3-thick-amd64 THICK or THIN Plugin?

Kindly clarify. Thank you.

Version 3.9.3 can actually run in both thick and thin modes.

Check out the deployment yaml in the release-v3 branch @ https://github.com/k8snetworkplumbingwg/multus-cni/tree/release-v3/deployments

Thanks for the reply. Yes, v3.9.3 is also having two separate deployment yamls for thin and thick. Even there are few difference between two yamls too. https://github.com/k8snetworkplumbingwg/multus-cni/tree/v3.9.3/deployments

As mentioned above, I have used thick-plugin's deployment yaml and expected the type to show as multus-shim (as in later v4.0.x). But still it is showing as mutlus as thin plugin. Hence the confusion raised. Is it only the naming is updated for thick ? Thanks for the support.
